Homebrew vulnerability analysis and mitigation
Overview
An issue has been found in function XRef::fetch in PDF2JSON 0.70 that allows attackers to cause a Denial of Service due to a stack overflow (NVD, GitHub Issue).
Technical details
The vulnerability exists in the XRef::fetch function of PDF2JSON version 0.70. When processing certain PDF files, the function enters into infinite recursion through ObjectStream::ObjectStream constructor calls, leading to stack overflow. The issue has been assigned a CVSS v3.1 Base Score of 5.5 MEDIUM (Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) (NVD).
Impact
The vulnerability can be exploited to cause a Denial of Service condition by triggering a stack overflow, which results in process termination. This affects the availability of the PDF2JSON service (NVD).
Mitigation and workarounds
As of the time of reporting, no official fix has been released. A potential workaround would be to increase the main thread stack size, though this is not a complete solution to the underlying recursion issue (GitHub Issue).
